Pilot Controlled Series
A pilot-operated valve uses an external auxiliary pressure relief valve—called a pilot—alongside the main valve to achieve more precise operation compared to conventional spring-loaded valves.

Pop-Action & Modulate-Action Difference
Kiatork has two types of pilot-operated safety valves.
Pop-Action: Opens fully at the set pressure with a complete lift.
Modulate-Action: Opens proportionally to the increase in system pressure for a more stable and efficient operating cycle.
